Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Frontend Components scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Frontend Components

This Skill provides Claude Code with specific guidance on how it should handle frontend components.

Instructions

  • Single Responsibility: Each component should have one clear purpose and do it well
  • Reusability: Design components to be reused across different contexts with configurable props
  • Composability: Build complex UIs by combining smaller, simpler components rather than monolithic structures
  • Clear Interface: Define explicit, well-documented props with sensible defaults for ease of use
  • Encapsulation: Keep internal implementation details private and expose only necessary APIs
  • Consistent Naming: Use clear, descriptive names that indicate the component's purpose and follow team conventions
  • State Management: Keep state as local as possible; lift it up only when needed by multiple components
  • Minimal Props: Keep the number of props manageable; if a component needs many props, consider composition or splitting it
  • Documentation: Document component usage, props, and provide examples for easier adoption by team members
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
